“As we have seen, one way in that zoologists have tried to avoid classifying same-sex activity as "homosexual" is by using terminology and behavioral categories that deny it is a sexual activity at all. This approach also extends to the interpretations, explanations, and "functions" attributed to same-sex behavior, even when it involves the most overt and explicit of activities. Astounding as it sounds, a number of scientists have actually argued that when a female bonobo wraps her legs around another female, rubbing her own clitoris against her partner's while emitting screms of enjoyment, this is actually "greeting" behavior, or "appeasement" behavior, or "reassurance" behavior, or "reconciliation" behavior, or "tension-regulation" behavior, or "social bonding" behavior, or "food exchange" behavior - almost anything, it seems, besides *pleasurable sexual* behavior. Similar "interpretations" have been proposed for many other species (involving both males and females), allowing scientists to claim that these animals do not really engage in "genuine" (i.e., purely sexual) homosexual activity. But what heterosexual activity is ever "purely" sexual?”
